Why to out bleed steam in turbine?
When steam contains liquid droplets while doing work at high temperatures, the water droplets can etch metal. To combat this, steam can be superheated or the pressure of the system is reduced.
Why is multistage used in steam turbine?
multistage is used because the expansion of high pressure steam will be gradual and as a result the rotor wont vibrate.suppose we have only 1 stage of blades in a turbine, hence all the steam will expand in the given stage and the speed of the rotor will be in high range around 30,000m/s, which is very difficult to control and operate the turbine.
What the inside of steam boiler?
"What the inside of steam boiler?" Would you like to know: with no water and steam, construction, under steam conditions, high loads, high TDS, Low pressure.
What is turbine windage protection?
when steam flow blockage occured in steam turbine due to damage of blades/nozzles than steam temperature will increase so protect the turbine from high temperature this protection is introduced.
Why would you not heat the steam coming out of turbine and feedback to turbine?
Steam is redirected back into the boiler from the high-pressure turbine for reheating, but the steam from the low-pressure turbine enters into a condenser to become water again.
How is electricity generated by using coal?
The coal is burned to boil water. The high-pressure steam is passed through the blades of a turbine, which turns an electric power generator.
Who invented high pressure steam broilers?
gumball who ivented high pressure steam broilers
How TO generate electricity from steam?
To generate electricity from steam, a steam turbine is typically used. High-pressure steam is directed onto the turbine blades, causing the turbine to spin. The spinning turbine is connected to a generator, which converts the mechanical energy into electrical energy.
What source of energy is used to make a large generator turn?
It is usually a steam turbine that powers a large generator, in which case it is the mechanical force caused by high pressure steam impinging on the turbine blades.
What is the pressure of high pressure steam?
will density of water is equal to density of steam at high pressures and temperatures
How does steam turbine works?
Steam or water, it works the reverse of a fan, where the fan pushes air down, the turbine is turned by the steam or water. there's a shaft leading from the turbine to the generator, which produces the electricity
What is the movement of the molecules in the high pressure steam?
In high pressure steam, molecules move rapidly and collide with each other and the walls of the container, creating pressure. This rapid movement is due to the high temperature of the steam.
What does steam do to a turbine?
Steam (under pressure) comes into contact with the blades of the turbine through which it is flowing and, by the direct application of force, causes the blades to move, turning the turbine shaft. The turbine coverts the thermal energy of the steam into (rotating) mechanical energy. Surf on over to our friends at Wikipedia using the provided link and get more info. Oh, and check out the pics! Answer it depends what type of turbine one is using types of steam turbine 1 impulse turbine 2 reaction turbine in 1 st one steam is completely expanded inside nozzle and all pressure energy get converted in to kinetic energy using this impulse force turbine runs. in 2nd steam is multiple stage blades are used where high pressure superheated steam gets expanded inside the turbine in each stage and after each stage velocity of steam increases. very high temperature superheated steam is reaquired because it has very high specific volume which helps in reducing mass flow rate of steam.
Why to out bleed steam in turbine?

What is the density of high pressure steam?
will density of water is equal to density of steam at high pressures and temperatures
What does the steam boiler do?
Boils water to create high pressure steam.
Who invented the high pressure steam engine?
It was NOT James Watt that invented the high-pressure steam engine. James Watt made very useful improvements to Newcomen's low-pressure steam engine, while several people experimented in the following years with high-pressure steam. It was Richard Trevithick, however, who invented the first proven, high-pressure steam engine, particularly in his Pen-y-Darren locomotive.
